ACTUAL EXAM TEST BANK 2026/2027
PATIENT CARE TECHNICIAN (PCT) FINAL EXAM PREP
VERIFIED QUESTIONS AND ANSWERS + DETAILED RATIONALES
A+ GRADED
This comprehensive test bank contains 250 carefully crafted examination questions
designed to prepare you for the DAVITA Patient Care Technician (PCT) certification
exam. The questions are organized to reflect the actual exam structure, with a
strong emphasis on complex hemodialysis scenarios, vascular access complications,
infection control protocols, and safety standards. Each question is accompanied by
a clear rationale to enhance your understanding of the underlying concepts. This
resource is intended for serious candidates who wish to master the material
through systematic review and practice. Work through these questions at your own
pace, focusing on areas where you need additional reinforcement. The questions
follow the actual exam format, testing both knowledge recall and clinical
reasoning skills essential for success in the dialysis setting.
Q1 ANALYZE COMPLEX HEMODIALYSIS SCENARIOS TO DETERMINE APPROPRIATE
NURSING INTERVENTIONS
During hemodialysis, a patient experiences a sudden drop in blood pressure and
complains of dizziness. The venous pressure alarm is silent, but the arterial
pressure is reading higher than baseline. Which of the following is the most
likely cause?
A. Hypovolemia due to excessive ultrafiltration
B. Arterial needle dislodgement
C. Venous needle infiltration
D. Air embolism
Correct Answer: A
Rationale: Hypovolemia from rapid fluid removal causes hypotension and dizziness
without altering access pressures. Arterial needle dislodgement would trigger a
venous pressure drop and air alarm; venous infiltration causes high venous
pressure; air embolism presents with respiratory distress and cardiac changes.
,Q2 ANALYZE COMPLEX HEMODIALYSIS SCENARIOS TO DETERMINE APPROPRIATE
NURSING INTERVENTIONS
A patient with a new arteriovenous (AV) fistula presents with a palpable thrill
and a continuous bruit on auscultation. However, the access appears swollen and
the patient reports pain at the site. What is the most appropriate immediate
action?
A. Apply a warm compress and continue monitoring
B. Notify the provider and hold dialysis on that access
C. Cannulate the fistula using a larger needle to reduce pressure
D. Administer anticoagulants to prevent thrombosis
Correct Answer: B
Rationale: Swelling and pain with a present thrill may indicate early stenosis or
pseudoaneurysm; dialysis should be held and the provider notified for further
evaluation. Warm compresses and larger needles could worsen injury;
anticoagulants are not indicated without confirmed thrombosis.
Q3 ANALYZE COMPLEX HEMODIALYSIS SCENARIOS TO DETERMINE APPROPRIATE
NURSING INTERVENTIONS
Which of the following best explains why a patient with chronic kidney disease
(CKD) develops hyperkalemia, and what is the most immediate intervention if ECG
changes appear?
A. Decreased aldosterone secretion; administer insulin with glucose
B. Increased potassium intake; administer sodium polystyrene sulfonate
C. Tissue breakdown releasing potassium; administer calcium gluconate
D. Reduced renal excretion; administer calcium gluconate
Correct Answer: D
Rationale: CKD reduces renal potassium excretion, leading to hyperkalemia. If ECG
changes occur, calcium gluconate is given immediately to stabilize cardiac
membranes. Insulin with glucose shifts potassium but is not the immediate
first-line for ECG changes; sodium polystyrene sulfonate acts slowly; tissue
breakdown is not the primary cause.
,Q4 ANALYZE COMPLEX HEMODIALYSIS SCENARIOS TO DETERMINE APPROPRIATE
NURSING INTERVENTIONS
A dialysis technician is preparing a patient for treatment and notes that the
patient's access is a central venous catheter. Which of the following observations
requires immediate discontinuation of the treatment?
A. Catheter exit site has slight crusting
B. Blood return is sluggish but present
C. Patient reports mild discomfort during flushing
D. Catheter lumen has a visible clot
Correct Answer: D
Rationale: A visible clot in the catheter lumen increases risk of embolism and
may compromise blood flow; treatment should be stopped and the catheter assessed.
Crusting, sluggish return, or mild discomfort may be manageable with proper
technique and monitoring.
Q5 ANALYZE COMPLEX HEMODIALYSIS SCENARIOS TO DETERMINE APPROPRIATE
NURSING INTERVENTIONS
Which of the following is the most critical factor in preventing central line-
associated bloodstream infections (CLABSIs) in dialysis patients?
A. Daily dressing changes with sterile gauze
B. Use of chlorhexidine-impregnated dressings
C. Strict adherence to hand hygiene and maximal sterile barrier precautions
D. Weekly catheter hub disinfection with alcohol
Correct Answer: C
Rationale: Strict hand hygiene and maximal sterile barrier precautions during
catheter insertion and care are the most effective evidence-based measures to
prevent CLABSIs. Chlorhexidine dressings and hub disinfection are adjuncts, not
the primary factor; daily dressing changes may increase risk if not done
aseptically.
Q6 ANALYZE COMPLEX HEMODIALYSIS SCENARIOS TO DETERMINE APPROPRIATE
NURSING INTERVENTIONS
A patient undergoing hemodialysis develops chest pain and shortness of breath.
The blood pressure is 90/60 mmHg and heart rate is 110 bpm. Which intervention
, should the technician prioritize?
A. Increase the ultrafiltration rate
B. Administer normal saline bolus
C. Place the patient in Trendelenburg position
D. Stop dialysis and assess for air embolism
Correct Answer: D
Rationale: Chest pain, shortness of breath, hypotension, and tachycardia during
dialysis may indicate air embolism. The immediate priority is to stop dialysis,
clamp the venous line, place the patient in left lateral decubitus position, and
administer oxygen. Increasing ultrafiltration would worsen the condition;
Trendelenburg position alone is insufficient.
Q7 ANALYZE COMPLEX HEMODIALYSIS SCENARIOS TO DETERMINE APPROPRIATE
NURSING INTERVENTIONS
A patient's dialysis machine alarms with a high venous pressure reading. The
technician observes that the venous needle site appears swollen and discolored.
What is the most likely cause and appropriate action?
A. Arterial stenosis; reposition the needle
B. Venous infiltration; stop dialysis and remove the needle
C. Clotted dialyzer; increase heparin dose
D. Kinked tubing; straighten the tubing
Correct Answer: B
Rationale: High venous pressure with swelling and discoloration at the needle
site indicates venous infiltration. The correct action is to stop dialysis, remove
the needle, apply pressure, and restart with a new site. Arterial stenosis would
affect arterial pressure; clotted dialyzer requires replacement; kinked tubing
would not cause swelling.
Q8 ANALYZE COMPLEX HEMODIALYSIS SCENARIOS TO DETERMINE APPROPRIATE
NURSING INTERVENTIONS
Which laboratory value would be most concerning in a patient with an AV fistula
who reports decreased sensation and pallor in the access arm?
A. Hemoglobin 10.5 g/dL
B. Serum potassium 5.2 mEq/L
